Be it known that I, FERNAND LAFFAY, a citizen of the Republic of France,now serving in the French Army, last residing at London, England, haveinvented certain new and useful Improvements in Type-Writing Machines,of which the following is a specification. I

My present invention relates to paper feeding mechanism for typewritingmachines and its general object is to provide new and improved mechanismof the character specified and by means of which novel results may beobtained.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, combinations of devices andarrangements of arts hereinafter described and particular y pointed outin the claims.

to Fig. e opera- Referring first to Figs. 1, 7 and 12, 1 indicatesstationary standards rising from the top plate (not shown) to whichstandards is fixed an inclined grooved track-way 2 which cooperatesthrough anti-friction balls 3 with the rear or slide bar 4 of a carriagetruck. Said truck further comprises end bars 5 rigid with the slide bar4 and providing open bearings for the axle 6 of a rotary platen 7 whichis mounted in a platen frame comprisin end ars 8 and connecting crossbars 9 an 10. aid platen frame together with the platen is adapted to berocked on the truck and is readily detachable therefrom, the frame andtruck together constituting a traveling platen carriage which iscontrolled by a motor and escapement devices of the ordinaryconstruction (not herein shown). Cooperative with. the platen at itsunder side are paper feeding devices 0 the usual construction comprisinga main feed roller 11 and a supplementary roller 12, the feed rollersbeing mounted on a frame 13 which is loosely pivoted on the bar 10.Guide fingers 14 are fixed to the frame bar 9 to guide the paperdownward at the rear of the platen. At the front side of the platen is acombined paper scale and guide bar or plate 15 which extends the fulllength of the platen and is mounted on arms 16 Specification of LettersPatent.

cated at 15*. Front paper guidin fingers on a ro .18 an- 17 are slidablymounted said fingers being ranged above the platen,

' carr1ers'22, said carriers being platen and advance the relationshiptherewith by pressed by springs 19 toward the platen and their lowerends overlying the scale late 15. Said rod 18 is supported at its en son arms 20 which are pivotally mounted on the end bars 8 and normallymaintained in fixed locking devices (not shown). In Fig. 1 1t will beobserved that the feed rollers 11, 12 do not extend throughout the fulllength of the platen. Outside of said. feed rollers are providedmarginal rolls 21 which are mounted on pivotally supported on the framerod 10. Springs 23 coiled around the rod 10 coiiperate with the carriersto press the marginal rolls 21 constantly' toward the platen. Thesemarginal rolls are not releasable by the regular releasing devices whichare provided for the middle or intermediate feed rollers 11 and 12. Saidreleasing devices comprise a rock shaft 24 bearing at its ends in thebars 8 and'provided at its left-hand end with a releasing arm or lever25. Fixed to said rock shaft are forwardly projecting fingers or lugs'26 which cooperate with the ledge or lip 13 on the frame 13 to movesaid frame downward when the release lever 25 is pulled forward as shownin Fig. 12, overcoming a leaf spring 27 which is confined between theframe 13 and the rod 10 and constantly tends to press said frame upwardand maintain the rollers 11 and 12 III cooperative engagement with theplaten. This releasing operation by the lever 25 also acts to throw offthe scale plate 15 which acts on the lower ends of the paper fingers 17to release said paper fingers.

The usual line spacing devices are preferably provided comprising a linespacing ratchet wheel 28 (Fig. 1) operatively connected to theright-hand end of the platen, said devices being operative to turn thepaper step-by-step.

My present invention is more especially concerned with supplementarypaper feeding or controlling devices or means next to be described forfeeding the paper continuously to predetermined extents as distinguishedfrom the ordinary step-by-step feed or advance communicated by the usualline spacing devices. Apair of posts, supports or round track-ways 29secured at their lower ends to the slide bar 4 by screws 30 are inclinedupward and rearward in the general plane of said slide bar, said postsbeingv spaced apart as appears from Figs-1 and 5 and connected at theirtops by a cross bar or rod 31 which lends stiffness and rigidity to theconstruction. The support a chute, clamping device or supplementarypaper feeding device comprising two plates 32 and 33 which are separatedor spaced apart by strips 34 arranged between the plates near theirends, screws 35 passing mouth 37 to the slot.

posts slidably' through said strips. and securing the plates and stripstogether, a narrow slot-way or opening 36 being two plates. At its up erend the front plate 32 is curled or bent f drward while the rear plate33 is bent backward at its upper end as clearly shown in Figs. 8, 9 and10 thus providing a comparatively wide or fiaring A cross bar or plate38 is arranged behind the plate 33 and the two are suitably fastenedtogether. The plate 38 is provided at its ends with tubular bearings 39which fit over and bear on the posts 29, the construction roviding foran easy sliding movement of the chute as a whole up and down on theposts or trackways 29. Upward movement of the chuteis limited by stopcollars 40 adjustably set on the posts near their tops and with whichthe upper ends of the tubular bearings 39 contact. The paper is adaptedto be fed downward into the slot-way 36' through the chute and in orderto control its passage through the chute, devices are providedcomprising spring fingers 41 secured by screws 42 to,the back of theplate 38, said springs being bent into abow-shape and their lower endportions being curved or rounded and tending constantly, through theinherent pressure of the springsthemselves, to enter the slotway 36through slotsor openings 43 cut 43 said curved ends are in register.Passing through the slots the curved ends contact with the inner face ofthe plate 32, as in Fig. 7, to clamp the paper lightly against saidplate or to such an extent as to prevent downward movement of the paperaccidentally or through its own weight. Consequently when the springfingers are in operative contact with the paper in the chute the paperwill be compelled to participate in any movement which may becommunicated to the chute without any change taking place in therelationship between the paper and the chute. In order to throw off thespring fingers 41 and clear the passage or slot-way 36, and at the sametime free the paper which may be within the chute, a transverse rockshaft 44 is arranged within the bow of the springs, said rock shaftbearing in brackets 45 secured to the plate 38 and being provided at itsright-hand end junction between the flats 44 and the roundthus providedbetween the.

In the under plate 33 and with which slots 44 of the A 'ed sides of theshaft will engage with the springs and act as a cam, forcing the springsdownward out of the slots 43 to the Fig. 9 position where the springsare entirely outside the slot-way 36, leaving the latter open andunobstructed throu hout its length so that paper may readily e insertedand advanced through the chute. Turning movements of the rock shaft .44are limited by step devices comprising a. lateral stop pin 45 on theright-hand bracket 45, which pin coiiperates with the sides of a notch44 cut in a flan e or collar 44 fixed to the rock shaft 44 ust outsidesaid bracket (Fig. 8).

The chute is controlled in its up and down movements by a train ofdevices comprising a lever 47 pivoted at 48 to a block or collar 49adjustably fixed to the left-hand post 29 (Figs. 1, 5, 7 and 10). Theright-hand arm of this lever inclines downward and inward and terminatesin a straight extension which normally is horizontaL' This straightportion coiiperates with a roller 50 arranged behind the cross bar 38 atabout the middle of its length. The roller is pivoted on a screw 51which also assists to secure in place on the plate 38 a downwardlyextending strip 52 terminating in an angular stop portion 53 which isadapted to cotiperate with the top of the slide bar 4 to limlt downwardmovements of the chute. A securing screw 54' at the lower end of thestrip 52 insures its rigidity on the plate 38. The screws 51 and 54 alsosecure in place a guide bar or strap 55 which is bent outward behind theroller 50 and provides a space 56 in which the inner straight portion ofthe lever 47 is loosely confined. The upper end of said straight portionengages with the under side of the roller and gives an anti-frictionconnection with the chute and one which permits straight or right linemovements of the chute while the lever 47 is moved pivotally. The freeend of the left-hand or shorter arm of the lever 47 is pivotallyconnected at 57 with the upper forked end of a vertically disposedextensible link 58, the lower end whereof is pivotally connected at 59with a horizontally disposed arm or lever 60, the construction andmounting whereof, together with that of the associate parts, is bestshown in Figs. 2 to 7. The left-hand end of the arm 60 is curved andshaped to provide a finger piece 61 while its righthand end is pivotedon a pivot screw 62 which is supported on a bracket or plate 63 fixed byscrews 64 to the slide bar 4. The tendency of the chute due to gravityis to run down its guide ways until arrested by the stop 53, thismovement raising the arm 60 to the Flg. 14 position. In order to holdthe chute raised in the Fig. 1 and Fig. 5 position, devices are providedwhich coiiperate with the arm 60 to hold it down as shown in erally froming preferably automatically controlled from the carriage release key 25and comprising a hook 65 which is pivoted at 66 to the inner face of theleft-hand end bar 5. A lateral pin 67 on said hook 65 underlies a flatspring 68 secured by screws 69 to the upper face of the end bar 5, thespring acting to maintain the hook in operative position. A link 70 ispivotally connected at 71 to the hook 65, said link being provided witha slot '72 having an open mouth 73, the slot engaging with a screw pin74 projecting latthe release lever 25. The open mouth of the slotprovides for readily detaching the link from the release lever and theslot provides for a lost motion connection between the link and therelease lever. Said connection permits a releasing movement of saidlever to throw ofi the feed rolls 11 and 12 without operativelyaifecting the link 7 O, the pin 74 on said lever traversing the slottoward its forward end during such releasing movement but not moving farenough to engage operatively with the forward end of the slot. However,when the releasing lever is pulled forward to its full extent it notonly acts to release the paper controlling devices which coiiperate withthe platen but also contacts with the end of the slot 72 and pullsforward the link 7 0, causing the latter to pull the hook 65 forward torelease the arm 60 and permit the chute to drop downward of its ownweight.

Means are provided for regulating and controlling the extent of downwardmovement of the chute when the hook 65 releases the lever 60, said meansas best appears in Figs. 1-3, 5, 6, 12-14 comprising a lever member 75pivoted on the screw 62 forward of the lever 60. To said lever 75 ispivoted at 76 an arm 77 having a forwardly off-set portion 7 7 at itsleft or free end, the off-set portion being provided with a slot 78which is adapted to coiiperate with a ,detent lug or nose 79 projectingforward from the inner end of a lateral pin the hook 65. When the hookis inoperative, however, the nose 79 is in rear of the slot 78 and doesnot engage therewith. The arm 77 has pivoted to it at 81 an upstandingarm 82 having a rearwardly bent top portion which carries an adjustablestop screw 83 that overlies a notch 60 cut in the lever 60 and operatesto limit upward movement of said lever in respect to the arm 77. The arm82 is provided with screw pin 85 projecting forward from an extension 75 0n the arm 75. Said screw 85 and slot 84 give a lost motion connectionbetween the arms 75 and 7 7 A pin 86 projecting from the rear of the arm75 is adapted to cotiperate with a notch 87 cut in the lower edge of thearm 60 to enable the lever 60 to a slot 84 which is engaged by a v 80 onthe inner face of pick up the arm or lever 75 during chute restoringmovements of the parts. Normally the arm 77 tends to drop dovs on itspivot 76 as a center until arrested by the engagement of the top of theslot 84 with the screw 85. Means are provided for changing this relativenormal' relationship between the arms 77 and 75, said means comprising a.cam arm 88 pivoted at 89 to a downward extension 7 5 on the arm 75,said arm 88 being provided at its upper end with a'curved or cam edge90. A stop pin 91 on the extension 75 limits movement of the arm88.toward the right and when said arm is in contact with said in the arm77 may swing downward until it is arrested by the slot 84 and screw 85.On swinging the arm 88 toward the left, however, be done by a fingerpiece 92 fixed to thearm and projecting forward therefrom, the cam 90contacting with the under face of the arm 77 will swing said arm upwardon its pivot 76 and hold it raised with relation to the arm 7 5. As aresult of swinging the arm 77 upward by this movement, the slot 78 isset above and out of register with the nose 79, as in Fig. 6. Thepurpose of this operation will be hereinafter explained.

When the cam 90 is swung to its rightward position the parts willnormally be related as in Fig. 5 and if at this tlme the release lever25 be pulled'forward or operated to a sufiicient extent the hook 65 willswing forward on its pivot 66, releasing the lever 60 and causing thenose 7 9 to enter the slot 78 in the arm 77. As a result of thisoperation the lever 60 will be free to swing upa ward on its pivot 62until arrested by the lines 32, 33

' screws 94: (Figs. 1 and 5). The

engagement of the notch 60 with the screw stop 83, this screw stop beingfixed at this time by reason of the engagementvof the detent or nose 79with the slot 78. The upward movement of the lever 60 results in acorresponding upward movement of the link 58, permitting the lever 47 toswing freely on its pivot and the chute or paper controlling device toslide downward on the guide ways 29 until arrested by the engagement ofthe notch 60 with the stop 83 at which time the parts will be in therelationship shown in Figs. 11 and 12. The 'new position of the chute isindicated by dotted in Fig. 1. Assuming that there is a work sheet(indicated in Fig. 1 by the reference letter 2) in the chute at thistime and clamped or controlled by the spring fingers 41,.the paper as aresult of this downward drop of the chute will be advanced downward overa guide plate 'or apron 93 fixed to the slide bar 4 between the posts 29by parts are so adjusted and regulated that proportioned,

is sufliclent to advance the this movement paper until the first linethereon is in posiwhich may conveniently tion for receiving the writing.If now the lever 25 be released it will return to normal position,permitting the parts that control it to return also to normal position,the hook and connected parts being restored b the spring 68. As a resultthe detent 79 wil disengage from the slot 78 permitting the arm 77 to beraised slightly by reason of the upward pull due to gravity on the lever60 actlng through the screw stop 83. This movement of the arm 77 willcontinue until the bottom of the slot 84 engages with the pin 85, thuspicking up the lever which will be revented from swinging upward by thehoo tion. quick enough to engage said lever 75. The parts will now be inthe position shown in Fig. 13. From an inspection of this figure it willbe observed that the slot 78 has been carried up so far that it is outof register with the detent 79. One or more lines may now be written onthe sheet 39 and if more than one line is written the sheet may beadvanced between the lines by operating the usual line space lever,causin the platen to turn and feed the paper t rough cooperation of thepressure rolls 11 and 12 with said platen. The writing having beenfinished the operator pulls forward on the release lever 25, throwingofi the pressure rollers and causing the hook 65 to disengage from thelever 75. The detent 79 being out of register with the slot 78 will passunder the arm 77 so that the parts are entirely free and the chute maydrop down of its own wclght until arrested by the stop 53, its newposition being indicated by dotted lines 32", 33" in Fig. 1. When thechute is thus arrested the operating arts will be in the positionillustrated in ig. '14, this movement causing a continuous advance ofthe work sheet p far enough to bring it to the point where it may besevered by means of theserrated edge 15*. In some classes of work it isnecessary, prior to restoring the chute operatlng parts to normalpositlon, to'throw ofl the s ring fingers 41, thus freeing the paperwithin the chute from itscontrol. .To return or reset the mechanism theoperator depresses the finger piece 61, causing a restoration of theoperating parts from the F 1g. 14 to the," Fig. 5 positlon and liftingthe chute from its lowermost to its upper or normal position. movementof the through the slot 8 the arm 75 and the arts the lever 60 actingand pin 86 will pick up parts supported thereby and restore them to thenormal position, the hook 65 snapping over the lever 60 and arm 75 whenthey have been moved downward far enough. The parts will now be setready for a repetition of the operations above outlined.

It will be observed that when operated as 65 which returns to normalposl- A During the return described, the novel mechanism permits twosuccessive advance movements of the chute and the work sheet p beforethe chute reaches its downward limit of movement. In other words, themovement of the chute from uppermost to lowermost position is divided,into two stages or steps between which the writing of the sheetcontrolled by the chute takes place. If it be desired to advance thework sheet continuously by a single movement of the chute from itsuppermost to-its lowermost position, this may be done by setting the cammember 88 in the Fig. 6 osition. This setting of the cam member li tsthe arm 7 7 so that the slot 78 is set out of register with the detent79. As a consequence if the lever be operated to free the arms 60 and 75from the control of the hook 65 the arts will move uninterruptedly fromthe Fig. 5 to the Fig. 14 position, causing a corresponding advancemovement of the sheet controlled by the chute.

The said sheet :0 is comparatively narrow and in some classes of work awider record sheet 12 (Fig. 1) is employed in addition, this recordsheet being controlled at its marginal portions by the rolls 21 and theoutside paper fingers 17. A carbon may be interleaved between the sheetsp and p or if preferred the back of, the outer sheet 71 may becarbonized so that the print on the outside or bill sheet p may beduplicated on the underlying record sheet. It will be understood thatthis record sheet 79 is not controlled by the chute and will only beadvanced throu h turning movements of the platen which ta e placeindependently of the chute just as feed movements of the chute areindependent of the platen. As a consequence, entries on the record sheetwill be condensed. While the novel mechanism above, described isprimarily designed for use in connection with bill sheets or receiptforms and record or day sheets, such as are used in the post oficesystems of foreign countries, Hungary, for example, it will beunderstood that the principles of the invention will readily lendthemselves to employment in connection with other characters oftypewritten work.

It will be observed that by my present invention there is provided asupplementary paper feed device, paper holder, which is adapted to feedthe paper over the platen first to one extent, and subsequently to afurther extent, the first feeding movement feeding the paper, work sheetor blank into positlon to receive the first line of writing, and thesubsequent feeding to said further extent advancing the completed blankout of the machine; that means are provided "for causing the chute orpaper holder ess, said means comprising in the present chute, papercarrier or' to feed paper over the v platen, while it and the carriageare motioninstance a finger piece or key that is mounted independentlyof the chute or paper holder'but is connected to transmit motionthereto; that the chute, holder or carrier maintains constantrelationship with the work sheet or blankduring the supplementary paperfeeding operation; that thisconstant relationship is maintained in thepresent instance by releasable means which holds the paper in fixedrelationship with the aperfeed device or holder, said releasa le meanscomprisin a pair of clamps and a finger. piece efi'ectlve to releasesaid clamps; that the chute or paper carrier is in the pres ent instancegravity-acting and is adapted to drop a plurality of times whereby thepaper 1s fed over the platen successively a plurality of extents; thatassociated with the gravity-acting paper carrier or device is handcontrolled latch mechanism for releasing said paper carrier, this latchmechanism being un er the control of a finger piece, in *the presentinstance the finger piece 25; and that the hand controlled latchmechanism is ada' ted to release the paper carrier successive y aplurality of times for advancing thev paper at desired intervals apluralityof predetermined extents.

Various changes may be made without dearting from my invention.
